Product details :
The AUTO LeakageTracking Test Machine / Tracking Index Tester is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator. Inside the well lit cabinet, a test specimen is placed on a glass plate and two platinum electrodes are lowered onto the top surface.
A gauge block is supplied with the instrument to ensure the electrodes have the proper distance between them. The table height is easily adjustable to ensure the proper angle of the electrodes and height of drops. The rest of the test is controlled from outside the test chamber with the door closed.
The voltage,limiting current, drip rate and number of drips are all set on the control panel. An operator should observe the test to see if a flame ignites. The instrument sounds an alarm if there is a tracking failure of at least two seconds.
